1. Ensuring Structural Integrity
- Essential pre‑service verification – confirms primary and secondary containment are free from defects, leaks, or weaknesses.
- Ensures tank can safely withstand internal pressures.
- Prevents environmental contamination and guarantees secure waste oil storage.
2. Testing Methodologies & Standards
- Pressurize inner tank with air – monitor pressure gauge for any drop.
- Apply soap solution over seams, welds, and fittings to visually detect escaping air bubbles.
- Ensures compliance with stringent industry standards and manufacturer specifications.
3. Interstitial Space Verification
- Thoroughly evaluate the interstitial space between inner and outer walls.
- Confirms secondary containment is properly sealed and capable of capturing potential leaks.
- Protects surrounding soil and groundwater from hazardous waste oil.
4. Regulatory Compliance & Safety
- Mandated by regulatory bodies – failure to perform pre‑use test results in legal penalties and environmental liabilities.
- Successful pressure test is a mandatory compliance step.
- Ensures safe and legal operation throughout the tank's entire lifecycle.
